This file defines the DenseSet and SmallDenseSet classes.
This file defines the SmallVector class.
Base class for scope-like contexts.
Implements a dense probed hash-table based set.
A base class to collect and print dropped debug information variable statistics.
DenseSet< const DIScope * > VisitedScope
A DenseSet tracking whether a scope was visited before.
LLVM_ABI void calculateDroppedStatsAndPrint(DebugVariables &DbgVariables, StringRef FuncName, StringRef PassID, StringRef FuncOrModName, StringRef PassLevel, const Function *Func)

LLVM_ABI void run(DebugVariables &DbgVariables, StringRef FuncName, bool Before)
Run code to populate relevant data structures over an llvm::Function or llvm::MachineFunction.
This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.
StringRef - Represent a constant reference to a string, i.e.
This is an optimization pass for GlobalISel generic memory operations.
std::tuple< const DIScope *, const DIScope *, const DILocalVariable * > VarID
A unique key that represents a debug variable.
DenseSet< VarID > DebugVariablesAfter
DenseSet of VarIDs after an optimization pass has run.
DenseSet< VarID > DebugVariablesBefore
DenseSet of VarIDs before an optimization pass has run.
